Ezi-Batten Corrugated sheeting has been assessed for suitability for use in non-cyclonic
roof and wall cladding applications in accordance to AS1562.1:2018, applicable to both
residential and commercial applications. Metallic coated materials comply with
AS1397:2011 and pre-painted materials comply with AS/NZS2728:2013. Installation of
product shall be in compliance with AS1562.1:2018 and SA HB-39:2015, National
Construction Code (NCC) and relevant QSM Technical Bulletins.

Ezi-Batten Corrugated sheeting will give excellent durability in almost all locations. It
is however important to choose the correct coating for each environment as shown in the
table below. Durability recommendations do vary based on the application of the product,
in roofing or walling installations. Please read the tables below carefully.

Roof Sheeting – Site Exposure Condition

Foot traffic limits for Ezi-Batten Corrugated sheeting are based on the accepted industry practice of designing traffic limitations on typical maintenance work. This equates to a single person with a small tool kit up to a total mass of 110kg (1.1kN load).
Walking on Ezi-Batten Corrugated profile requires that feet are placed evenly over at least two ribs. Walk as close as practical to the supports or ideally walk directly on the screw line.

* Severe marine begins 100 – 400m from the coast and may extend inland depending on
local conditions.

These are general guidelines only. Building location, design and aspect need to be
taken into account. To ensure warranty will be given, check with Ezi-Batten before
using in these areas.

Due diligence needs to be applied to ensure that all materials are compatible. Corrosion may occur when incompatible materials are either in direct contact, immersed in a common electrolyte, receive inert drainage or drainage from incompatible materials.
As a general rule for metallic coated and pre-painted materials, always avoid direct contact with copper, lead, tantalised timber, Monel, uncoated steel, stainless steel and concrete/mortar.
Drainage from inert materials must not flow onto galvanised material. Inert materials include glass, aluminium, glazed ceramic tiles, pre-painted steel and metallic coated steel.
More highly corrosive environments require additional care, the effects of marine and industrial environments can extend long distances from the source and create unique corrosive challenges.

• *
  Roofing and cladding materials that are not exposed to rainfall should be washed
  down at least once every six months (more often in marine environments) to remove
  build-up of corrosive elements.
• *
  Prior to installation, materials must be kept clean and dry. Ensure that sheeting
  packs are covered, air flow is adequate to eliminate condensation and water is not
  allowed to pond. Should materials get wet, sheeting must be separated and thoroughly
  dried.
• *
  Sheeting should be handled with care to both avoid installer injury and damage to
  the product. Cutting of sheets must only be done with tin snips, shears or
  cold-cutting saw, so as to avoid the damage caused by abrasive cutting methods (i.e
  angle grinder).

Wind Pressure Limit State Capacities – 5 Fasteners per Sheet

Table based on testing in accordance to AS1562.1:2018, AS4040.0:1992 (R2016) and AS4040.2:1992 (R2016, Amd.1 2018), to be used in conjunction with AS1170.2:2011 (R2016). Internal spans must have both end spans reduced by 20%. Roof sheets are to be fastened with minimum 12 gauge screw and wall sheets are to be fastened with minimum 10 gauge screw, having a non-conductive sealing washer and minimum corrosion resistant coating of Class 4 per AS3566. Table based on fixing to minimum steel support thickness of 1.50mm BMT.

Fastener Selection

Fastening screws are to be hex head and must be fitted with a non-conductive sealing washer for both roof and wall applications. Screws must conform to AS3566 with a corrosion resistant coating to Class 4 as minimum. Use of load spreading washers for high wind zones and for the fixing of flashings is encouraged. Fastener lengths specified below are based on using 60mm blanket, thicker insulation may require increased screw lengths.

Corrugated Screws (Non-Cyclonic only)
Wind Pressure Limit State Capacities – 3 Fasteners per Sheet

When fixing to steel section of 0.75mm BMT or less, use Type 17 or proprietary hybrid point screw. Metal self-drilling screws (such as Buildex® Teks®) should not be used in steel less than 1.0mm BMT. Buildex® Roof Zips® may be used both in steel (up to 1.9mm) and timber.

Buildex® Designer Head Zips® may be used both in steel (up to 1.9mm) and timber. Designer Head Zips® are an ideal solution for valley fixing Corrugated, resulting in a pleasing and discrete finish.
